Shannon's capacity

WebbThe Shannon capacity models the amount of information that can be transmitted across a noisy communication channel in which certain signal values can be confused with each other. In this application, the confusion graph or confusability graph describes the pairs of values that can be confused. For instance, suppose that a communications channel has … Webb6 maj 2024 · As a result, a fiber that had a maximum capacity of 38.4 Tbps (at 400 Gbps per wavelength) can now support 48.0 Tbps. Using our US$4 million example in Figure 1, the cost-per-gigabit will be further reduced from US$104 to US$78. Source: Huawei. Figure 2: Spectrum in C-band

Analysis: R = 32 kbps B = 3000 Hz SNR = 30 dB = 1000 ∴ 30 = 10 log SNR Using shannon – Hartley formula C = B log 2 (1 + …
